Beginning work on ticket charger
- right now just validates two things are present
- perhaps use virtus to be sure of the types?
Build up the ticket charger some more.
- #total returns the total price of all the tickets
- #external_charge_id= sets the external charge id on each ticket
- #charge! is responsible for telling the charger to actually charge stripe
	- not done yet
	- it will take the response returned from charger.charge! and set the external charge id
Coveralls wear rails.
Get the external charge id from the charge.
Add stripe.
Plan for a charger collaborator.
Begin implementation of charger
- need to handle failure
- added empty charge class because virtue wants it
- charge needs to be defined still
Add some stripe responses we can test against.
Hook up to stripe.
Rename card to token, set error to stripe error.
Add failure tests for stripe.
- make charger accessible on ticket_charger
- add the ability to comment/uncomment things for testing against Stripe API
- rename stuff in tests because of token v. card
Silence hound.
